My invention relates to axle bearings especially to axle bearings for locomotive drive cup and cone.

The housing 3- is provided with a circular axles and other railway vehicle axle constructions. The invention has for its principal objects a construction which is strong and rigid and which is easily assembled and disassem-' bled; The invention consists principally in providing an axle housing with an annular series of bosses in its interior adapted to cooperate with bosses on a ring in said housing, said ring constituting an abutment for the outer race member of an antifriction bearing. The invention further consists in a housinghaving an internal tubular projecting portion whosefend is normally slightly spaced away from the end of the inner bearing member of said roller bearing. The in-' vention further consists in the axle bearing and in the parts and combinations and arrangements of parts hereinafter described and claimed.

' 7 In the accompanying'dra'wing wherein like reference numerals refer to like parts wher ever they occu r Fig. 1 is a part elevation, part vertical sec-1 tional' view of a locomotive drive axle construetion embodying my invention,

Fig. 2 is a part sectional view on the line 2'2 of Fig. 1,' 1

a Fig. 3 is a sectional view on'the line 3-3 of Fig. 1-, and

Figs. 4 and 5.are detail views showing the bossed cup abutment ring and the cooperatingbosses-in the axle housing.

In the drawing is illustrated a'loeomotive drive axle 1 having drive wheels 2 on each. end. A hollow axle housing 3 is provided for. said axle and antifriction bearingsare interposed between the enlarged tubularend por- 'tions4 of said housing and the axle 1. The

drawing'illustrates-a taperiroller bearing at each end of the axle housing, each bearing comprising amp 5 or outer bearing member mounted in the housing, a cone 6 mounted on 7- between sald the axle and conical rollers I seriesof projecting. bosses 8'around its inner periphery that normally abut against bosses 9 on a ring10 disposed in the tubular end the end mm which said plugs have been re-' portion 4 and abutting against the bearing cup 5. v The lower portion of the housing has a flaring portion 11 extending from the midnected to the bearing seat portion by means of a radial web 12,- In said web 12 are removable plugs 13 that project into the spaces between the bosses of said housing and the bosses of said abutment ring, thus preventing rotation of said ring relative to the housing.

Mounted between the inner bearing member 6 and the wheel 2 is a sleeve 14 that is en: gagedby the wheel 2, to hold the bearing cone 6 in position. Thus the bearing is firmly held I in position. i The end of the housing is closedby a ring 15 securedthereto by cap screws 16 and having a grooved inner. peripheral portion 17 encircling said cone securing sleeve 14.

After the parts have been assembled and the abutment ring 10 locked'in position by means of the plugs 13, the parts of the device are firmly held in position. The body portion of the housing has aninternalpro ecting sleeve portion 18 that is normally spaced slightly away, say one-eighth inch, from the end of the bearing cone. In order to disassemble the device, the locking plugs13 are removed from oneend of the housing, and using is moved endwise away from the moved? A tool is then inserted through the 5 plug holes and the abutment ring 10 is loosened from itspinched position between the bearing cup 5 and the housing 3. The abutment ring 10 is then turned until its bosses register with the spaces between bosses of the housing so that the abutment ring can be v moved out of contact with the bearing cup. The cap screws 16 are then removed andv the 'whole structure placed in-a wheel press with theram 3O engaging the end of the axle and the backing bars 31 engagingthe Web'p'oras The tion or other suitable portion-of the housing 3 to prevent movement of the housing. ram is then actuated. Movement of the ram at first carries with it all parts of the bearing until-the end of the bearing cone 6 -is seated against the projecting inner tubular portion 18- of the housin The cup is suihciently loose in the housing to permit this movement and said movement is accommodated by the releasing of the cup abutment ring. After the bearing cone is seated against the tubular portion of the housing, further thrust is memes her in the operation of disassembling the structure.

Signed at Sept. 1928 taken up on the housing and the bearings at I one end are removed. In similar fashion the bearings at the other end may then he re The above described construction has numerous advantages. After the parts are assembled. thev are firmlv held in place during normal running 'conditi on and still theymay be easily disassembled when required. Oh-

viously numerous changes might be madewithout departing from the invention. and'l do not wish to be limited to the precise construction shown.

' What I claim is:

' 1..An axle hearin'q' construction comm-isinsr an axle. a housing therefor havinq' an enlarged tubular end portioma roller bearinQ" interposed between said axle and said tuhular end portion. said tuhular'end portion -ha'vingan' annular series of bosses around.

its inner nerip'herv and a ring: in said tubu lar end nortion against which the outer hearing memher of said hearing ahuts. said ring; having bosses engaging the bosses of said axle housing.v

f 2. An axle hearing construction comprising".

an axle. a housinr'r therefor having an enlarged tubular end portion. a roller bearing in erposed between said axle and said tubular end portion. said tubular end. portion having an annular series of bosses around its inner perinheryaa rinq in said tubular end Dortion against which the outer bearing member of said hearing abuts, said ring having. bosses engaging the bosses of said axle housing and removable means extending into spaces between said bosses to prevent rotation of said ring.

3. An axle bearing construction comprisins: an axle. a housing therefor having an enlarged tubular end portion, a roller bearing interposedbetween said axle and said tubular end portion, said tubular end portion having an annular series of bosses around its inner periphery and a ring in said tubular end portion against which the outer bearing member of said bearing abuts, said. ring having bosses engaging the bosses of said axle hous:
